Electrical resistivity of antiferromagnetic GdP

Abstract The electrical resistivity of GdP single crystals has been measured between 4.2 and 300 K as function of the stoichiometry. The metallic type of resistivity exhibits critical scattering of electrons at the Neel temperature. Within the range of stoichiometries investigated, the type of scattering changes between “Ornstein-Zernike” like and “Fisher-Langer” like. The magneto-resistance is negative.
